Sad question

[kross]

I was happy when a few of my female crs got pregnant and release the shrimplets suscessfully. Now I can see some crs shrimplets. :) However, good news was soon followed by bad news..... All the females that released the shrimplets had died one after another!! :(

My friend read some article about shrimps dying after releasing the eggs. So, my question is.... is it true? Or is it due to other reasons? The rest of the shrimps including the male crs are alright..... so far.... :undecided

I think it is merely coincidence?

I don't think releasing the eggs might result in death. It's kinda don't have any link for me. The eggs are attached at the legs and babies get out of the legs. No internal organs or whatever used, so I guess no physical harm at all? And releasing the eggs is not like giving birth like mammals, don't think much stress is present. :)

However, that is just my views. I may be wrong as it's based on purely my thinkings. :p Hope experts here can clarify for you. :)

I am no expert, but I want to say something. :)

I encounter quite frequently death of female Crystal Red Shrimp in process of mating to shrimplet birth. In other words, matured females die easily, I am not sure if it is right after releasing the babies.

Kross, how's the baby shrimps doing?

[retardo]

I agree with Walter. I don't believe there's any kind of link between releasing eggs, molting, and death. It's quite hard to pinpoint cause of death in shrimps though, so I wouldn't rule that out. CRS as very particular about water conditions, from what I've read, so any slight change in their environment may cause them to be stressed and die as a result. Sorry to hear of your losses.

Hi,
it is not true that CR are super sensitive. Yes, they are not as hardy as other shrimps but can adopt well to sub-optimal conditions and even breed for generations in such conditions. There are much more sensitive shrimps.

I experienced the same phenomenon that my females die while or after carrying eggs. But it happens to e.g. tiger shrimps as well and seems to have something to do with the individual itself, not with the whole species. In the same tank last week a tiger shrimp died after her first batch while an old CR female is still alive and healthy after her third batch.

Best regards

Hi all, quite a few of my female cherries died after carrying eggs for a couple of days and I am really pulling my hair out as I have exhausted all possible cost of their deaths and am still unable to find a good explainination! :undecided The male cherries, tigers and other shrimps are doing fine. Water parameter is excellent (ph, kh, temp, NH3, NH4 all in good readings). But thinking back, I wonder if those stuffs attched to the dead female cherries' legs are empty egg cases (successsful hatching) or unhatched eggs? :huh:

Thanks for sharing your experiences guys.

Hi fruitpie, the shrimplets are doing ok... Growing pretty fast. However, the survival rate was low... 3 females released their eggs and only manage to see 5 shrimplets, max, at one time so far....

I also suspects that I got high mortality rate for CRS shrimplets. :embarasse

My Cherry shrimplets are doing fine. Maybe the type of plant makes a difference. I have Crypt and Anubias in the tank. Could it be the reason? :cry:

Won't tigers and crystal reds interbreed?

[Robert]

Hi,
yes they could do it but my ones do not interbreed (at least not in the last 3 years)and this tank is a special tank just for pregnant females and shrimplets. So there are only females who gave birth and lots of tiny shrimplets. It's a 20l tank just for them because I want to breed my tigers after a certain plan and the CR shrimplet also have a better survival rate than in the other breeding tank where also cherry shrimps are (because of a much smaller population).

Hi,

er... very new to shrimps, definitely no expert :( , but could it that a smaller ratio of females to males be the reason for mature female shrimp deaths? This may cause stress to females due to the males harassing them... that's the case with many animals...

[Robert]

Hi,
normally male shrimps do not harass the females that much. Sometimes you can see the males very actively swimming thru the tank, that is a normal behavior because then try to mate almost every other shrimp of their species. Such "mating dances" of the males are short, often only some hours long. In this time females know how to protect themselves and try to hide most of the time. I never saw any dead female shrimp after such evening.

Best regards

I saw a tragic which a old female shrimp just after molting was raped to death by a group of males, the female shrimp was chased by a few male. It was nice to see the mating process, but sad to see a corpse in a few hour later.

[WhiteSheep]

I guess the moral of the story where females die of harassment is the same... provide more plant covers and mosses :worried:.

[gigahertz]

Can you guys share the normal expected # of shrimplets for CRS from an adult female shrimp assumign that the shrimp is healthy and the water condition is optimal.

I currently have 3 pragnant females carry eggs and I just want to see what I can potentially expect.

Comparing my numbers and what everyone else is getting should tell me if my tanks condition is optimal for CRS reproduction.


Thx!!!
